Fix build server only deploys arm64 macOS binaries

[MrStevns]

We do this for now by introducing more mac os runners. This means that we deploy proper arm64 builds now as well as x86_64.

Ideally we would build universal binaries but Homebrew does not support building cross platform, as such we would have to build Qt ourselves in order to support this.

Note: We have to remember to make changes to the website, so we can see both new build types
